[tomsrtbt] sync,umount problem

[Gernot.Fink]

I think that the problem with sync/umount is caused by the lua before it.

There is a readfrom("|du 1") T=read("*n") which opens a process in the background.
This background-prozess has $MP as rootdir.
A readfrom() should close _INPUT and terminate this prozess.
 

This modified snip works:


        RI=floor(1.125*(T-UI))
        UI=floor(1.125*UI)
        readfrom("|du 1") T=read("*n")
        readfrom()
        Z1=(2*T)+10
        OA=floor((Z1+1)/2)
        print("RZ="..RZ)
        print("RI="..RI)
        print("UZ="..UZ)
        print("UI="..UI)
        print("Z1="..Z1)
        print("OA="..OA)
        '>>$ID/ST
cd $ID
.. ST
sync
umount $MP
